Good questions
Frequently asked
How long does a kitchen extension take?+
Typically eight to fourteen weeks on site after design and approvals.
Do you also do kitchens?+
We have a sister company that specialises in kitchens to allow you to have the most seamless experience possible. You can also use any kitchen company you like!
How much does a kitchen extension cost in the UK?+
The cost of a kitchen extension in the UK depends on several factors, including the size of the extension, the specification. As a guide, a high-quality single-storey kitchen extension typically starts from around £45,000 with larger or more bespoke projects costing more. At Alpine Extensions, every quotation includes a free home consultation, 4D virtual design, planning permission (where required), building regulations, structural calculations and a complete design and build service. We provide a fixed quotation before work begins, so you know exactly what's included.
Do I need planning permission for a kitchen extension?+
Not always. Many kitchen extensions can be built under Permitted Development Rights, meaning planning permission may not be required. However, this depends on factors such as the size of the extension, your property's location, whether it's detached, semi-detached or terraced, and if your home is in a conservation area or is a listed building. For a general rule of thumb - houses that are detached can project from the rear of the property up to 4m without planning permission houses that are semi detached can project from the rear of the property up to 3m without planning permission
Will a kitchen extension add value to my home?+

Open-plan kitchen, dining and living spaces remain one of the most desirable features for homebuyers, making a well-designed extension a worthwhile investment.
